The computer generation of holograms is a rendering method which enables the use physiological depth cues as stereopsis, motion parallax and visual accommodation at realistic images synthesized by Computer Graphics. Starting from a geometrical description of the scene, the algorithm determines interference patterns under specific conditions, which are put into photographic films to make the holograms. The holography reconstruction process involves the interference pattern observation under specific conditions. Through backlight illumination the holograms reconstruct the real and the virtual images of the scene presenting, simultaneously, psychological depth cues. Considerations of hidden elements, implemented by ray-casting, reduce the stored information as well as improve the realism of the holographic images, favoring the tridimensional perception of the reconstructed holographies.
